[jira] [Created] (NIFI-4798) UpdateAttribute should allow empty string values without requiring state management

Mark Bean created NIFI-4798:
-------------------------------

             Summary: UpdateAttribute should allow empty string values without requiring state management
                 Key: NIFI-4798
                 URL: https://issues.apache.org/jira/browse/NIFI-4798
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework, Extensions
    Affects Versions: 1.5.0
            Reporter: Mark Bean


The conditional validation of dynamic properties in UpdateAttribute use the NON_EMPTY_STRING validator when state management is not enabled. This prevent the "Set empty string" checkbox option. The introduction of state management to this processor changed this behavior which previously allowed an empty string for an attribute value. The validator for the non-stateful case should be changed to return the original behavior.
